A myotome is the group of muscles that a single spinal nerve innervates. [1] Similarly a dermatome is an area of skin that a single nerve innervates with sensory fibers. Myotomes are separated by myosepta (singular: myoseptum). [2] In vertebrate embryonic development, a myotome is the part of a somite that develops into muscle.
Treatment for the common occurrence of ulnar neuropathy resulting from overuse, with no fractures or structural abnormalities, is treatment massage, ice, and anti-inflammatories. Specifically, deep tissue massage to the triceps, myofascial release for the upper arm connective tissue, and cross-fiber friction to the triceps tendon.
Surgery is the most common method of treating peripheral nerve sheath tumors. [11] In malignant tumors, complete resection is the only known curative treatment (with a sufficiently wide margin or even amputation to improve prognosis). [12] For larger lesions or those with a more aggressive histology, adjuvant radiation is recommended. Novel or ...
This joint is a so-called saddle joint (articulatio sellaris), unlike the CMC joints of the other four fingers which are ellipsoid joints. [17] This means that the surfaces of the TMC joint are both concave and convex. This shape provides the TMC joint a wide range of motion. Movements include: [18] Flexion; Extension; Abduction; Adduction ...
Anderson and colleagues from St Thomas' Hospital, London, were the first to mention a case with possible clinical findings of LEMS in 1953, [11] but Edward H. Lambert, Lee Eaton, and E.D. Rooke at the Mayo Clinic were the first physicians to substantially describe the clinical and electrophysiological findings of the disease in 1956.
Radiofrequency ablation (RFA), also called fulguration, [1] is a medical procedure in which part of the electrical conduction system of the heart, tumor, sensory nerves or a dysfunctional tissue is ablated using the heat generated from medium frequency alternating current (in the range of 350–500 kHz).
Syndrome of inappropriate antidiuretic hormone secretion (SIADH), also known as the syndrome of inappropriate antidiuresis (SIAD), [2] is characterized by a physiologically inappropriate release of antidiuretic hormone (ADH) either from the posterior pituitary gland, or an ectopic non-pituitary source, such as an ADH-secreting tumor in the lung.

Malignant peripheral nerve sheath tumors are a rare type of cancer that arise from the soft tissue that surrounds nerves. They are a type of sarcoma. Most malignant peripheral nerve sheath tumors arise from the nerve plexuses that distribute nerves into the limbs—the brachial and lumbar plexuses—or from nerves as they arise from the trunk. [5]
